Gifford Grapnel
Dynamic Load Monitoring Ltd. (DLM)
The Gifford Grapnel is usually used in conjuction with the Rennie. It is made up in units of four hooks at right angles to each other. The hooks resemble a crane hook with a broad hook seat to form a cup to hold the hooked cable. It can be used on any type of bottom but originally designed for rocky or coral environments.
